DSC HSM2955 PowerSeries Neo Two-Way Audio Module

Deliver reliable audio verification and faster incident response for your monitored sites with the DSC PowerSeries Neo Two-Way Audio Module HSM2955. Designed for professional security integrators and monitoring stations, this two-way audio module supports four independent audio stations, enabling live voice interaction and verification that reduces false alarms and accelerates dispatch decisions. The HSM2955 can optionally record up to 15 minutes of pre-alarm audio to provide crucial context leading up to an event, and supports both VOX and push-to-talk workflows to fit your standard operating procedures. For discreet response to duress or hold-up alarms, the module offers a silent listen-in mode that activates only during an alarm. Built for robust deployments, it operates over PSTN or cellular networks and integrates natively with PC5961E small and PC5964E large audio stations. Ideal for alarm monitoring centers, retail, banking, and critical infrastructure, the DSC HSM2955 enhances surveillance, monitoring, and on-site communication without complex rewiring.
